Description
int strpos ( string $haystack , mixed $needle [, int $offset = 0 ] )

Returns the numeric position of the first occurrence of needle in the haystack string. Unlike the strrpos() before PHP 5, this function can take a full string as the needle parameter and the entire string will be used. 

Parameters
haystack:    The string to search in

needle:    If needle is not a string, it is converted to an integer and applied as the ordinal value of a character.

offset:    The optional offset parameter allows you to specify which character in haystack to start searching. The position returned is still relative to the beginning of haystack.


Return Values
Returns the position as an integer. If needle is not found, strpos() will return boolean FALSE.
